Abstract Aim: This study aimed to evaluate the effect of High-Intensity Interval Training (HIIT) on the skeletal muscle of Spontaneously Hypertensive Rats (SHR). Method: In total, 20 male rats, SHR, 12 months old, were used, distributed into 2 groups: Control Group (C) and Training Group (HIIT). The training lasted approximately 50 minutes/day, 5 days/week, for 8 weeks. Systolic blood pressure (BP) was measured at the beginning and end of the study. Analysis: The medial gastrocnemius muscle was used to measure the smallest fiber diameter, after which the Shapiro-Wilk normality test was performed, followed by the Mann Whitney test to compare the medians and interquartile intervals (IQI) of the muscle fibers and Student t-test for performance. For analysis of BP, Analysis of Variance - ANOVA was used, followed by Tukey's post-test. All procedures adopted a significance value of 5% (p < 0.05). Results: The median values for the variable “smallest diameter” of muscle fibers were 29.48 (IQI: 9.96) µm in the C group and 33.45 (IQI: 9.44) µm in the HIIT group (p < 0.05). Also, the performance was increased in the trained animal group and blood pressure values decreased significantly at the end of the experiment (p < 0.05). Conclusion: The HIIT intensity promoted an increase in the median values of the muscle fibers and performance. Finally, a significant decrease was observed in blood pressure variation values.

Abstract Background: Chronic leg ulcers affect a large portion of the adult population and cause a significant social and economic impact, related to outpatient and hospital care, absence from work, social security expenses, and reduced quality of life. The correct diagnosis and therapeutic approach are essential for a favorable evolution. Objective: To gather the experience of Brazilian dermatologists, reviewing the specialized literature to prepare recommendations for the diagnosis and treatment of the main types of chronic leg ulcers. Methods: Seven specialists from six university centers with experience in chronic leg ulcers were appointed by the Brazilian Society of Dermatology to reach a consensus on the diagnosis and therapeutic management of these ulcers. Based on the adapted DELPHI methodology, relevant elements were considered in the diagnosis and treatment of chronic leg ulcers of the most common causes; then, the recent literature was analyzed using the best scientific evidence. Results: The following themes were defined as relevant for this consensus - the most prevalent differential etiological diagnoses of chronic leg ulcers (venous, arterial, neuropathic, and hypertensive ulcers), as well as the management of each one. It also included the topic of general principles for local management, common to chronic ulcers, regardless of the etiology. Conclusion: This consensus addressed the main etiologies of chronic leg ulcers and their management based on scientific evidence to assist dermatologists and other health professionals and benefit the greatest number of patients with this condition.

Abstract Lupus miliaris disseminatus faciei or acne agminata is a chronic inflammatory disorder of the skin, considered an intriguing entity due to its pathogenesis, which is still largely speculative. It has been linked to tuberculosis, sarcoidosis, rosacea, and other granulomatous diseases, but it is considered an independent entity.

SUMMARY: Severe muscle injuries are common in accidents and have a delayed recovery of muscle integrity. In these cases, muscle suture surgery is the standard treatment. However, Platelet Rich Plasma (PRP), has been widely used in orthopedic injuries due to its growth factors. Thus, the objective of the study will be to analyze the association of suture and PRP techniques in the collagen and tenacity of the injured muscle. Were used seventy rats, divided into five groups: control (C), injury control (CI), injury and suture (IS), injury and PRP (IP), injury, suture, and PRP (ISP). Were sectioned approximately 50 % of the width and 100 % of the thickness of the gastrocnemius muscle. The homologous PRP was applied 24h after the injury. On the 7th day after the injury, the animals were euthanized and their muscles subjected to mechanical testing to measure tenacity or collagen analysis to calculate the ratio between type I and III collagen. The results show a significant decrease (p <0.05) in the values of the relationship between collagens in all injured groups (CI, IS, IP, ISP) compared to group C. In injured groups, the tenacity was significantly (p <0.05) reduced compared to the control group, with no observed difference between treatments and injured groups. The amount of collagen in the injured area has increased, but it did not affect the tenacity of the muscles, which was reduced.

RESUMEN: Las lesiones musculares graves son comunes durante los accidentes y la integridad del músculo está sujeta a una larga recuperación. En esos casos la cirugía, para la sutura del músculo, es el tratamiento común, no obstante el plasma rico en plaquetas (PRP) ha sido utilizado recientemente en lesiones ortopédicas, debido a sus factores del crecimiento. El objetivo del estudio fue analizar la asociación de las técnicas de sutura y PRP en la histología y tenacidad de músculo lesionado. Fueron utilizadas 70 ratas distribuidas en cinco grupos: control (C), control lesión (CL), lesión y sutura (LS), lesión y PRP (LPRP), lesión, sutura y PRP (LSPRP). Aproximadamente en la lesión, el 50 % de la longitud y el 100 % del espesor del músculo gastrocnemio fueron seccionados. El PRP homólogo fue aplicado 24 horas después de la lesión. En el 7º día después de la lesión los animales fueron eutanasiados y las muestras fueran sometidas al ensayo mecánico para la medición de la tenacidad y análisis del colágeno, para realizar el cálculo de la relación entre los colágenos I y III. Los resultados demostraron una reducción significativa (p<0,05) en los valores de la relación entre los colágenos en todos los grupos lesionados en relación al grupo C. La tenacidad fue (p<0,05) reducida significativamente en los grupos lesionados en relación al grupo control, sin diferencia entre los tratados. En la lesión muscular hubo disminución de los valores de colágeno, aunque en los tratamientos se observó elevación de la cantidad de colágeno en la área lesionada, esta no tuvo efecto en la tenacidad de los músculos que fue disminuida en la lesión.

Resumo Fundamento A síndrome de takotsubo (takotsubo) é uma forma de cardiomiopatia adquirida. Dados nacionais sobre essa condição são escassos. O Registro REMUTA é o primeiro a incluir dados multicêntricos dessa condição no nosso país. Objetivo Descrever as características clínicas, prognóstico, tratamento intra-hospitalar e mortalidade hospitalar e em 1 ano de seguimento. Métodos Estudo observacional, retrospectivo, tipo registro. Incluídos pacientes internados com diagnóstico de takotsubo ou que desenvolveram esta condição durante internação por outra causa. Os desfechos avaliados incluíram fator desencadeador, análise dos exames, uso de medicações, complicações e óbito intra-hospitalar e em 1 ano de seguimento. O nível de significância adotado foi de 5%. Resultados Foram incluídos 169 pacientes, em 12 centros no Estado do Rio de Janeiro. A idade média foi de 70,9 ± 14,1 anos e 90,5% eram do sexo feminino; 63% dos casos foram de takotsubo primário e 37% secundário. Troponina I foi positiva em 92,5% dos pacientes e a mediana de BNP foi de 395 (176,5; 1725). Supradesnivelamento do segmento ST esteve presente em 28% dos pacientes. A fração de ejeção do ventrículo esquerdo teve mediana de 40 (35; 48)%. Observamos taxa de 25,7% de ventilação mecânica invasiva e 17,4% de choque. Suporte circulatório mecânico foi utilizado em 7,7%. A mortalidade intra-hospitalar foi de 10,6% e a mortalidade ao final de 1 ano foi de 16,5%. Takotsubo secundário e choque cardiogênico foram preditores independentes de mortalidade. Conclusão Os resultados do REMUTA mostram que takotsubo não se trata de patologia benigna como se pensava, especialmente no grupo de takotsubo secundário que acarreta elevada taxa de complicações e de mortalidade.

Abstract Background Takotsubo syndrome (TTS) is an acquired form of cardiomyopathy. National Brazilian data on this condition are scarce. The Takotsubo Multicenter Registry (REMUTA) is the first to include multicenter data on this condition in Brazil. Objective To describe the clinical characteristics, prognosis, in-hospital treatment, in-hospital mortality, and mortality during 1 year of follow-up. Methods This is an observational, retrospective registry study including patients admitted to the hospital with diagnosis of TTS and patients admitted for other reasons who developed this condition. Evaluated outcomes included triggering factor, analysis of exams, use of medications, complications, in-hospital mortality, and mortality during 1 year of follow-up. A significance level of 5% was adopted. Results The registry included 169 patients from 12 centers in the state of Rio de Janeiro, Brazil. Mean age was 70.9 ± 14.1 years, and 90.5% of patients were female; 63% of cases were primary TTS, and 37% were secondary. Troponin I was positive in 92.5% of patients, and median BNP was 395 (176.5; 1725). ST-segment elevation was present in 28% of patients. Median left ventricular ejection fraction was 40 (35; 48)%. We observed invasive mechanical ventilation in 25.7% of cases and shock in 17.4%. Mechanical circulatory support was used in 7.7%. In-hospital mortality was 10.6%, and mortality at 1 year of follow-up was 16.5%. Secondary TTS and cardiogenic shock were independent predictors of mortality. Conclusion The results of the REMUTA show that TTS is not a benign pathology, as was once thought, especially regarding the secondary TTS group, which has a high rate of complications and mortality.

Background: In Brazil, mathematical models for deriving estimates and projections of COVID-19 cases have been developed without data on asymptomatic SARS-CoV-2 infection. We estimated the seroprevalence of antibodies to SARS-CoV-2 among blood donors in the State of Rio de Janeiro. Methods: Data were collected on 2,857 blood donors from April 14 to 27, 2020. We report the crude prevalence of antibodies to SARS-CoV-2, the weighted prevalence by the total state population, and adjusted prevalence estimates for test sensitivity and specificity. To establish the correlates of SARS-CoV-2 prevalence, we used logistic regression models. The analysis included period and site of blood collection, sociodemographic characteristics, and place of residence. Results: The proportion of SARS-Cov-2 positive tests without any adjustment was 4.0% (95% CI 3.3-4.7%), and the weighted prevalence was 3.8% (95% CI 3.1-4.5%). Further adjustment by test sensitivity and specificity produced lower estimates, 3.6% (95% CI 2.7-4.4%) and 3.3% (95% CI 2.6-4.1%), respectively. The variable most significantly associated with the crude prevalence was the period of blood collection: the later the period, the higher the prevalence. Regarding socio-demographic characteristics, the younger the blood donors, the higher the prevalence, and the lower the educational level, the higher the odds of a positive SARS-Cov-2 antibody. Similar results were found for the weighted prevalence. Discussion: Although our findings resulted from a convenience sample, they match some basic premises: the increasing trend over time, since the epidemic curve in the state is still on the rise; the higher prevalence among the youngest who are more likely to circulate; and the higher prevalence among the less educated as they have more difficulties in following the social distancing recommendations. Despite the study limitations, it is possible to infer that protective levels of natural herd immunity to SARS-CoV-2 are far from being reached in Rio de Janeiro.

SUMMARY: Rheumatoid arthritis (RA) is a disease triggered by environmental and genetic factors. Research suggests that physical exercise has benefits such as delaying functional disability. In vivo studies using experimental models of arthritis can provide useful information about these benefits. to analyze the effects that different intensities of aquatic physical exercise have on the proprieties of the bones in induced arthritis in knees of Wistar rats. Male Wistar adults rats (n=20) were divided into 5 groups: Group Control Arthritis (GCA) n=4, Group control Placebo (GCP) n=4, Group Low Physical Activity (GB) n=4, Group Moderate Physical Activity (GM) n=4 and Group Intense Physical Activity (GI) n=4. The physical activity groups got an intra-articular injection of Zymosam on the right knee; the GCA received saline solution in the right knee; the GCP was submitted to the stress of the needle. The animals were submitted to aquatic activity for 30 minutes, 4 times a week for 5 weeks, and the intensity of the exercise was determined by a weight placed on their back: GB=1 %, GM=5 %, GI=15 % of their body weight. It was observed that the group GB, and the groups that did not exercise GCA and GCP, gained more weight compared to the group GM. In relation to the bone mineral content of the tibia, there was a decrease in the GM group when compared to the GCP group, whereas in the tibial bone mineral density there was a decrease in the GM group compared to the GCP, GCA, GB. As for the area of the femur, the GI group presented an increase of it compared to the GB and GM groups. It is concluded that the high intensity exercises promote better results in bone properties.

RESUMEN: La investigación sugiere que el ejercicio físico tiene beneficios como retrasar la discapacidad funcional de la artritis reumatoide. Los estudios in vivo que utilizan modelos experimentales de artritis pueden proporcionar información útil sobre estos beneficios. Se analizaron los efectos de las intensidades del ejercicio físico acuático sobre las propiedades de los huesos, en la artritis inducida en las rodillas de ratas Wistar. Las ratas Wistar macho adultas (n = 20) se dividieron en 5 grupos: grupo de control artritis (ACG) n = 4, grupo control placebo (CGP) n = 4, grupo de actividad física baja (GB) n = 4, grupo de actividad física moderada (GM) n = 4 y grupo de actividad física intensa (GI) n = 4. Los grupos de actividad física recibieron una inyección intraarticular de Zymosam en la rodilla derecha; el GCA recibió solución salina en la rodilla derecha; el CGP fue sometido a la tensión de una aguja. Los animales fueron sometidos a actividad acuática durante 30 minutos, 4 veces a la semana durante 5 semanas, y la intensidad del ejercicio se determinó mediante un peso colocado sobre su espalda: GB = 1 %, GM = 5 %, GI = 15 % de su peso corporal. Se observó que el grupo GB, y los grupos que no ejercitaron GCA y CGP, ganaron más peso en comparación con el grupo GM. En relación con el contenido mineral óseo de la tibia, hubo una disminución en el grupo GM en comparación con el grupo GCP, mientras que en la densidad mineral del hueso tibial hubo una disminución en el grupo GM en comparación con el GCP, GCA, GB. En cuanto al área del fémur, el grupo GI presentó un aumento en comparación con los grupos GB y GM. En conclusión el ejercicio de alta intensidad promueve mejores resultados en las propiedades óseas.

Abstract This was a cross-sectional study to start a cohort in two University Hospitals of two countries – Brazil and Colombia – for assessing the prevalence of needlestick and sharps injuries (NSI), the level of compliance with standard precautions (SPs), and knowledge on blood borne pathogens and associated factors among health students and professionals, within the framework of the implementation of the NR-32 standard. We created compliance scales based on 12 and 10 questions, for assessing knowledge. We used the Multinomial Poisson-Tweedie Regression to evaluate the relationship between knowledge and compliance with SPs within NSI. We evaluated 965 individuals (348 students and 614 professionals). The mean score points for level of knowledge was 10.98, with a median of 11 (10; 12) and α-Cr of 0,625. Compliance with SP had a mean of 30.74 and median of 31 (28; 34), with a α-Cr coefficient of 0.745, associated with country, group (student) and risk perception. Among the factors associated with the report of NSI, we singled out knowledge and compliance, country of origin, and full vaccination scheme against the Hepatitis B virus. We concluded that the level of knowledge and compliance were adequate among participants, but better among Brazilian participants, and it was associated with NSI reporting.

Abstract The article analyzes the labor market of nursing assistants and technicians in the State of Ceará, Brazil, from 2013 to 2017, concerning job insecurity aspects. Two data sources were employed. The cross-sectional Brazilian Nursing Team Profile Survey (PPEB) was used as the baseline, and the longitudinal Annual List of Social Information (RAIS) database, allowed the study of the trend of some of the variables related to job insecurity. Given the small number of similar studies for this professional category, we opted for an exploratory data approach that supported a critical discussion of the results. The job insecurity of nursing assistants and technicians is supported by empirical evidence in the four perspectives adopted by the International Labor Organization-ILO: time-related, economic, social, and organizational. While it is a market with a positive balance of admissions compared to layoffs, jobs have low salaries, poor work relationships, high turnover, lack of prospect of career advancement, and adverse working conditions such as exposure to violence, discrimination, and accidents. We can conclude that RAIS data corroborate the PPEB findings, and point out that there is no trend of improvement for this situation.

Resumo O artigo analisa o mercado de trabalho de auxiliares e técnicos de enfermagem no Ceará, nos anos de 2013 a 2017, nos aspectos relacionados à precarização do trabalho. Duas fontes de dados foram empregadas. A Pesquisa sobre o Perfil da Equipe de Enfermagem no Brasil (PPEB), de caráter transversal, foi utilizada como linha de base, e a Relação Anual de Informações Sociais-RAIS, longitudinal, possibilitou o estudo da evolução de algumas das variáveis relacionadas à precarização do trabalho. Dada a pequena quantidade de estudos semelhantes para essa categoria profissional, optou-se por realizar uma abordagem exploratória que subsidiou uma discussão crítica dos resultados. A precarização do trabalho de auxiliares e técnicos de enfermagem é sustentada por evidências empíricas nas quatro perspectivas adotadas pela Organização Internacional do Trabalho-OIT: temporal, econômica, social e organizacional. Embora seja um mercado com saldo positivo de admissões em relação aos desligamentos, os empregos apresentam baixos salários, vínculos precários, alta rotatividade, ausência de perspectiva de ascensão e condições adversas de trabalho, como exposição a violência, discriminação e acidentes. Conclui-se que os dados da RAIS corroboram os achados da PPEB e apontam que inexiste qualquer tendência de melhora dessa situação.
